ABSTRACT:
An article conveyor comprises a pair of belts, each trained around a pair of pulleys, with straight stretches between said pulleys. The four straight belt stretches are coplanar and parallel. One pulley for each belt is so driven that the belts move in opposite orbital directions. Corresponding stretches of the two belts are confined to lengthwise motion, as by additional freely rotatable pulleys or by a rail-like member for each of said stretches having a groove in which the belt is slidingly received. Each article carrier has belt engaging portions with long, laterally oppositely opening grooves in which said belt stretches are received, so that said stretches support and drive the carrier.
